Science Fair Projects on Absorbency

When you think about science fair projects on absorbency you most likely think about paper towel experiments. While these are viable science experiments and projects, they don't corner the market. There are a lot of objects that have an absorbent personality including rocks, sponges, natural fibers and synthetic fibers. Below you will find a few ideas for projects that you can complete.

Natural sponges are more absorbent than synthetic sponges. This hypothesis will require you to develop science fair projects on absorbency that compare how much moisture natural sponges can absorb to the amount that synthetic sponges can absorb. In this experiment the independent variable will be the type of sponge you use and the dependent variable will be the amount of liquid that the sponge is able to absorb. What did you find out?

Rocks can absorb water. This is an interesting hypothesis that you can test with geology rocks science fair projects. In this experiment the independent variable will be the various types of rocks you experiment with and the dependent variables will be the ability of the rock to absorb water.

The third option that you have for science fair projects on absorbency will take a look at the absorbency of paper towels. In this experiment you will see if the claims made by the leading paper towel companies that they paper towel absorbs more than their competition. The independent variable for this experiment will be the brand of paper towel and the dependent variable will be the amount of liquid the paper towel is able to absorb. A variation on this experiment will be to test which paper towel is indeed the "quicker picker upper.

Another experiment that you can complete will test the absorbency of human skin. For this experiment you will test how long it takes for hand lotion to be absorbed into the skin. You will need volunteers of different ages for this experiment. Your hypothesis will be that older skin is more absorbent than younger skin. Your independent variable will be the age of the person you are testing and the dependent variable will be the amount of time it takes for the hand lotion to be absorbed.

Each of the above experiments and projects can be modified and advanced. All you have to do is take each one to the next level or to take it in a new direction. For example, you can use the data from the rock absorbency experiment to explain how waterfalls are created or explain why some rocks are mossier than others. The key to developing an advanced project is to think creatively and to apply raw data to a new situation.
